To all whom it may camera."

Be it known that I, STEPHEN E. PARRISH, a citizen of the United Statesof America, residing at Hillsdale, in the county of Hills dale and Stateof Michigan, have invented certain new and useful Improvements inlnsulating'Jackets for lee-Cream Pails, of which the following is aspecification, reference being had therein to the accompanying drawings.

lln the present state of the art ice-cream and other ices areextensively sold in paper pails and packages which latter have become anestablished article of commerce. These pails or packages are suitablefor the carrying of the ice a short distance and where itis intended forimmediate consumption, but they do not afitord any protection againstthe heat and consequently will not preserve the ice for any length oftime. On the other hand where the ice is not intended for immediate useit is customary to pack it in salt and ice which greatly increases thebulk of the package as well as endangering the spoiling of the contentsthrough leakage of salt water into the inner receptacle.

it is the object of the present invention to utilize the standardconstruction of paper pail or package and without materially increasingits size or weight to provide a heat insulation sufficient to preservethe contents for a much longer time.

- To this end the invention consists, first, in the combination with anordinary paper an. pail or package of commerce, of a detachable, closelyfitting heat insulating jacket and further in the peculiar constructionof said jacket as hereinafter set forth.

In the drawings-Figure 1 is a perspective view of the jacket. Fig. 2 isa fragmentary vertical section of the jacket with the pail inclosedtherein. Fig. 3 is a horizontal section through a portion of the jacket;Fig. t is a perspective view of elements used in the construction ofthe'jacket. 1F ig. 5 is a frag mentary perspective, view of the. cover;and Fig. 6 is a fragmentary perspective view of the inner paperreceptacle.

lln the construction of my improved heat to linsulating jacket it is theobject to secure the maximum efficiency with as little increase in thebulk of the package as possible and also with an inexpensiveconstruction to manufacture. This I obtain by first forming an outercasin A preferably of paper or paper board an having at its upper end ametallic binding B. Within this outer casing is a lining C which llpreferably form of thin wood veneer and preferably of two bent sections,one forming the opposite sides C, C and the bottom C and the other thesides 0* C and an overlapping bottom C. These sections are arranged atright angles to each other and thus line the four sides of thereceptacle. Between the lining U and the outer casing is interposedcorrugated paper D which forms a series of air cells or pockets andholds the lining out of direct contactwith the outer casing.

E is a paper lining inside of the lining C and preferably rendered waterproof by paraffin or other suitable'coating. The metallic binding B ispreferably formed with a laterally bent portion F which forms a shoulderfor supporting the cover of the package and also having a downwardlybent portion G which overlaps the lining E of the package.

H isthe cover preferably formed of a plurality of sheets of paper boardH and interposed layers of felt H 1 are fastening devices for holdingdown the cover which as shown are formed by rods or wires having eyes lfslidably and pivotally engaging apertures in the binding B, while theopposite ends of the wires detachably engage apertures l in the metallicbinding.

J is a ring for lifting the cover from the jacket, and K is a bail bywhich the package may be carried. p

The jacket constructed as just described is proportioned to fit thestandard size of paper pail M which latter when inserted in the jacketwill closely fit the same and will permit of placing the cover H in itsproper position. In use the paper package M is first filled with the icethen inserted in the jacket, the cover is placed in position and islocked by engagement of the rods or wires T with the apertures 1?. Thiswill effectually seal in the cold air which fills the cells or spacesformed by the corrugated paper, with the result that the conduction ofheat through the walls of the jacket is very slow. Thus, even with asmall package such for instance, as a pint pail, the ices may be kept ingood condition for a number of hours.

l Vhat ll olaimas my invention is:

1. A heat insulating jacket comprising an inner and an outer wall,cellular spacing -means therebetween, a metallic binding having a returnbent flange embracin the outer Wall, and a lateral portion exten ingacross the space between the walls, and a cover for the jacket seatedupon the laterally' extend- 5 ing portion of the binding.

2. A heat insulating jacket comprising a paper double walled receptacle,a metallic binding for the upper edge of the receptacle having a returnbent portion embracing the 10 outer paper wall, and a lateral inwardlyextending portion, a cover for the receptacle seated upon said laterallyextending portion, and locking means secured to the binding strip forsecuring said cover to its seat.

- In testimony whereof I affix my signature 15 in presence of twoWitnesses.
